JOSEPH J. KU LAGE, OF ST. LOUIS, MISSOURI.

BRICK-MACHINE.

EiPEOIFICATlION forming part-of Letters Patent No. 347,355, dated August 17, 1886. 7 Application filed December 19, 1884. Serial No. 150,723. (No model.)

To all whom it may concern:

Be it known that I, J OSEPH J. .KULAGE, o

St. Louis, -Missonri,'have made a new and useful Improvement in Brick-Machines, of which the following is a full, clear, and exact descrip tion.

' The improvement is useful in many forms of brick-machines, and especially in connection with a portion of the brick-machine shown in a pending application of 'mine for Letters Patent, filed May 9, 1884.,and allowed September 5, 1884. The portion referred to is that part of the structure used in transmitting the motive power to those parts which are immediately associated with the plungers; and the present improvement relates to those means im mediately employed in operating the pl ungers.

The annexed drawings, making part of this specification, illustrate this improvemenu'and include those parts of the machine which are essential to an understanding of the improvement.

Figure 1 is a vertical longitudinal section on the line 1 1 of Fig. 3. Fig. 2 is a rear end elevation, and Fig. 3 is a horizontal section on the line3 3 of Fig. 1.

The same letters of reference denote the same parts. i

A A represent the two gear-wheels, attached, respectively, to the shafts B B, and united by means of the wrist-pin D, forming a crank, substantially as in the construction above referred to. The pitman E, however, in place of, at its forward end, being connected with a cross-head adapted to work in slides, is jointed to a lever, F. This lever is of a doublebell-crank type, is journaled at f in the frame G, and its arms f f are respectively jointed to the links G G and H H. The lower links,-

G, in turn are jointed to the upper plunger, J. The upper links, H, in turn are 3' ointed to a cross-bar, I, which is adapted to be moved upward and downward in the slots 0 c in the frame 0. p

K K represent links connected with the Crossbar, and leading thence past the upper plunger to the cross-bars or lugs jj, to which the lower plunger, J, is attached. The frame 0 is slottedat c c,to admit the bars j j,which are adapted to be moved upward and downward therein. The lower plunger works upward and downward at c in the frame 0, and

the original construction referred to, by means of the rods m m,which extend from the charger to the bell-crank levers m m, journaled at m in the frame 0, and moved reciprocatingly in their beari ngs. and so as to operate the charger, by means of the guides a c upon the wheels A A, respectively.

The lever F and links G- H in effect constitute a double toggle. As the wheels A A are rotated, the pitman E causes the lever F to turn upon its bearingf, and the toggles to be straightened-that is, the lever-armsff and the links G and H are moved into line with each other and with the plungers. The movement causes the upper plunger to be thrust downward,and thelower plunger to be drawn upward, the upward motion of the links H H and cross-bar I being, through'thelinks K K, transmitted to the cross-bars j and lower plunger, J. As the rear end of the lever F passes above the level of the bearing f, the toggles act to separate the plungers, and thus for every revolution of the wheels A A the plungers are closed together and opened apart. No strain, beyond that of supporting the parts, comes upon the frame Gin operating the plungers, for the pressure upon the bearing f is balanced and the main stress is sustained by the toggle and links K K. The lever F can be extended, as desired, to increase the leverage upon the toggle, and the wheels A A and pitman E are usefulnot only for operating, but also for increasing the efficiency of the toggle. It will also be noticed that the toggle is arranged above the table L, upon which the clay is worked. This serves to keep the toggle free from the trouble arising from the dirt getting into the joints of the working parts. The wheels A A" are driven by the pinions P 1? upon the shaft 1?. After the bricks have been pressed, the lower plunger, by means similar to that shown in the construction above referred to,but nothere shown, I becomes attached to the upper plunger, and therefore when the upper plunger rises it lifts the lower plunger with it, and the lower plunger is thereby caused to eject the bricks from the 1nolds,and after they are ejected the charger in its movement operates to move the bricks out of the way, and also to detach the lower plungerqvhieh then drops. To provide for this movement of the lower plunger the links K K are suitably slotted, (not shown in the drawings,)-that is, as the lower plunger is lil'ted by the upper plunger the armsj y move upward in the slots in the links K K, and when the lower plunger is detached the armsjj drop to the lower end of the slots.

I claim-- 1. In a briekunachine, the comhinatiomwith the frame and the upper and lower pluugers, ot' a bell-ernnk lever supported upon a fixed pivot in the frame, a set of toggles for forcing down the upper plunger, and a second set 01. toggles and connecting-rods forsinmltaneously raising the lower plunger to compress the clay, all said parts being supported by the single fixed pivot,whereby both plungers are moved an equal distance and the frame relieved of strain, which is transferred entirely to the working parts, the frame being provided with guides for keeping the extremities of the upper and lower toggles and said connectingrods in the same vertical line with the pivot and the plungers, substantially as set forth.

2. The combinationof the double-bellcrank lever, mechanism for oscillating the same, the upper and lower plungers, links connecting the lower end oi'thelever with theupper plunger, the frame having a guiding slot or way, 0, a cross-bar, 1', fitting in said way, links con neeting the upper end of the plunger with said cross-bar, and links ll ,con11eeti|igtlie crossbar with the lower plunger, the lower plunger being movable vertically relative to the links K K, and the plungers being provided with devices for temporarily locking them together, substantially as set forth.

\Vitucss my hand this 16th December, 1884.
